Application filed May 18, 1905. Serial No. 260,989.

To all whmn it may concern.-

Be it known thatI, GEORGE L. JMILLER, residing at Socialville, in the county of Warren and State of Ohio, have invented'certain new and useful Improvements in Tire Bolting, Boring, and Drilling Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in machines for turning nuts on and 0E tire-bolts, boring the felly, and means for drilling the vehicle-rim or other objects; and the invention primarily has for its object to provide a machine of this character of a very simple and effective construction which can be easily operated and which will readily and effectively serve its intended purposes.

Generically myinvention includes a main shaft, a pair of drive-pinions thereon, a pair of drive-shafts geared with said main shaft, a drill-carrying shaft geared. with said main shaft, means for moving the drill-carrying shaft longitudinally on its axis toward or from the objects being worked upon, and an anvil member vertically adjustably held on a supporting-base and arranged so as to be moved toward or from the drill-shaft to allow for work of diflerent thicknesses.

The invention also includes a supplemental anvil member having means cooperating therewith for holding the wheel thereon and having means for engaging the bolt to prevent its turning while the nut is being screwed on or unscrewed, such supplemental anvil member being detachably secured to the main anvil member, so that it can be bodily removed therefrom, together with the wheelholding and bolt-holding devices.

WVith other objects in view than have been heretofore enumerated the invention comprises certain novel construction, arrangement, and combination of parts, all of which will be first described in detail and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my invention. Fig. 2 is a vertical longitudinal section thereof,showing the parts adjusted ready to receive a wheel and showing the anvil in dotted lines to receive larger work. Fig. 3 is a similar view showing the parts adjusted with the wheel in position, the wheel-holding clamp engaging the wheel-rim and the bolt-holder engaging the bolt. Fig. 4 is a cross-section on the line 4 4 of Fig. 2. Fig. 5 is a horizontal section on the line 5 5 of Fig. 2. Fig. 6 is a similar view on the line 6 6 of Fig. 2. Fig. 7 is a detail perspective view of the supplemental anvil member looking at it from the under side. Fig. 8 is a perspective view of my machine with the supplemental anvil member removed and showing how the same may be used for drilling or boring ordinary metal plates. Figs. 9 and 10 are modified views hereinafter specifically referred to.

Referring now to the accompanying drawings, in which like numerals of reference indicate like parts in all of the figures, l represents a base which is adapted to be secured to a post or other suitable support and which is provided with a pair of longitudinal extensions 2 and 3, spaced a suitable distance apart. The extensions 2 and 3 are each provided with a pair of apertures 2 2 and 3 3 respectively, the corresponding apertures 2 3 and 2 3 respectively, alining with each other. The main shaft 4 passes through the apertures 2 and 3, while the drill-shaft 5 passes through the apertures 2 and 3 and the shafts 4 and 5 extend parallelly to each other.

The upper end of the drill-shaft 5 is provided with an annular groove 5 to receive a key-pin 6 of a cap-bearing 6, which fits on the shaft end and which has an apertured lug 6 to be straddled by arms 7 7 of the bifurcated lever 7, a bolt 7 serving to pivotally connect the lever 7 to the lug 6'. The lever 7 is so arranged as to permit the main shaft 4 passing up between its bifurcated arms 7 7 a when desired.

1 designates a slot in the base 1, in which a short link 8 is fulcrumed, as at 8. The link 8 has a bifurcated end 8 to receive an end 7 of the lever 7 ,to which it is pivotally connected by a bolt or pin 8, as clearly shown ICC the bearing 6 serving to normally hold the drill-shaft 5 up with the tool 33 above and out of engagement with the work.

Mounted on the main shaft 4 between the extensions 2 and 3 is a sleeve 12, which carries a beveled gear 12 to mesh with the beveled pinion 13 on the upper drive-shaft 13, which is mounted in a bearing 13*, connected with the extensions 2 and 3, and which projects to one side of the machine and has a squared end 13 to receive a crank or other power-applying device 14. The main shaft4 has a groove 4 to receive a key 12 of the sleeve 12, so as to connect the sleeve 12 and the shaft 4 to turn together, but still allow longitudinal movement of the shaft 4 through the sleeve 12. 15 designates a gear on the shaft 4 between the extension 2 and the sleeve 12, which gear also has a key for entering the groove 4 and which gear 15 also meshes with a gear 16 on the drill-shaft 5. The gear 16 has a key 16 to enter a groove 5 of the shaft 5, whereby the shaft 5 and the gear 16 will rotate together and still allow of longitudinal movement of the shaft 5 through the gear 16.

2O designates the main anvil, which has a securing-base adjustably mounted on base 1 by bolts 20 20, which pass through a slot 1 in the said base 1. The anvil 20 has a slotted portion 20, forming a bifurcated end 20 20 22 designates a bearing portion in the anvil 20 to receive the forwardly-extending driveshaft 23, which carries adrive-pinion 23, that meshes with a drive-pinion 23 on the main shaft 4, and which has a squared end 23" to receive a crank 14 or other power-applying drive mechanism.

24 represents a collar on the shaft 4 adjacent the anvil 20 to hold the shaft 4 from longitudinal movement with respect to the anvil 20, so that when the anvil 20 is adjusted up or down the shaft 4 and the anvil 20 will move together.

26 designates a supplemental anvil which comprises a body portion 26*, having a longitudinal slot 26", in which the bolt-holding member 27 is pivotally secured, as at 27 The bolt-holding member 27 has a bolt-engaging stud 27 b at the free end.

26 26 designate the sides of the anvil 26, which straddle the main anvil 20 and which have apertures 26 26 to receive the securing pin or bolt 27, which also passes through apertures 20 in the bifurcated end of the main anvil 20 to secure the supplemental anvil 26 to the main anvil 20.

Mounted on the bolt 27 c between the bifurcated end of the anvil 20 in the slot 20 is a cam-lever 28, whose cam portion 28 is adapted to engage the bolt-holder 27 to force it against the bolt-head. The cam-lever 28 also has a bifurcated portion 28 to receive a link 29, which connects with the lower cross-bar 30 of a rectangular frame 30, whose side bars 30' 30 straddle the anvils 20 and 26 and project up above the top of the anvil 26, the top bar 30 of the frame 30 being provided with wheel-engaging fingers30 30 to hold the wheel down on the anvil when the lever 28 is manipulated. The bars 30 30 extend between the ends of the sides 26 26 and studs 31 31 of the anvil 26.

32 designates a rod secured to the support in a position above the machine to receive the wheel-hub.

So far as described, the manner in which my invention operates can best be explained as follows: If it is desired to use my machine as a bolting-machine, I secure a wrench member 33 to the drill-shaft 5 by a set-screw 33, as shown. The wheel is then put in place on the rod 32, as shown in Fig. 1, in an upright position to rest on the anvil 26, the wheel being turned until the proper bolt is in position under the drill-shaft and above the anvil. The operator then moves the wheel with a bolt directly under the drill-shaft and depresses the treadle, which causes the wrench 33 to engage the nut. The crank 14 is secured to the machine drive-shaft 23, which when turned causes the shaft 4 to turn the drill-shaft 5, and thereby turn the wrench 33 to enable the nut to be screwed on or off, as the case may be. Should a bolt in the wheel-rim turn during the foregoing operation, it is only necessary to raise the lever 28, when the wheel-rim, will be firmly grasped by the fingers 30 and held tightly against the anvil, while the bolt will beengaged by the stud 27 of the boltholder 27 and held from turning. After the nut has been removed the wheel is drawn for ward on the anvil 26, where it will be in the position to permit driving the bolt out of the wheel.

From practical experience I have found that in old wheels the bolts become very tight, in some cases requiring the services of a helper to hold the wheel while the bolts are being driven out. With my machine no helper is required, as the wheel rests on a solid base, thus saving time and expense.

The adjustability of the anvil permits wheels of different sizes to be used on one machine, the anvil being adjusted up or down to take the particular size rim that is being operated. upon.

The double drive shaft mechanism employed by me is essential, as the two drive- -shafts greatly enlarge the scope of work the machine is able to do, as either shaft can be IIO used by the operator in his work, depending upon the position in which he is standing while working the machine.

When my invention is used for any other purpose than tire-bolting, the anvil 26 is removed from the machine, leaving the anvil 20 in position to receive any material to be 0perated upon for general drilling or boring, and when my machine is used as'a drilling and boring machine I remove the-wrench 33 and place a drill in its place. Again, when my machine is used as a drilling and boring machine the crank 14: is applied to the upper drive-shaft instead of to the machine, if desired.

By the use of my invention newly-painted wheels can have their burs or nuts removed or applied without the danger of scratching the paint on the wheel, as the work is always in plain view at all times and no part of the woodwork of the wheels comes in contact with the machine.

In Fig. 9 I have shown how a square shaft 4 or 5 may be used, and when the shaft 4 is made square, as shown in Fig. 9, the gear 15 is provided with a hub 12, which enters the bearing-aperture in the member 2, and the sleeve 12 is provided with a hub 12' to enter the bearing-aperture in the member 3. In this form the stop 24 is also provided with a hub 24 as shown.

In Fig. 10 I have shown a further modified form of my invention in which an intermediate gear 61, on a stud-shaft 61 is provided to permit the shafts 4 and 5 being spaced a greater distance apart than in the forms shown in Figs. 1 2, and 3 in the drawings.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my invention will be readily understood by those skilled in the art to which it appertains.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
